Linux/Unix Process Trees and Process Hierarchy

Sleep is an executable that we can use to simulate a blocking process for the purposes of demonstrating how to handle child processes.

Here's our base case.

The execution pattern is going to occur in this way: zsh (interactive) -> bash (./parent.sh) -> bash (./child.sh) -> sleep. Because both Bash processes performed an exec without fork, the bash (./parent.sh) process will be replaced by Bash (./child.sh), which itself will be replaced by sleep. This will mean that there are no child processes to manage except for the immediate child of sleep. Upon sending SIGINT, the sleep process will be terminated, and there will be no resource leak. No orphaned nor zombie processes.

./parent.sh:

Installing .NET 5 in Amazon Linux 2 for ARM64

This is a way to install .NET 5 in your home directory without modifying the system.

At the time of this writing, Amazon Linux 2 for ARM64 almost works already, but there is a problem with the ICU library. I will show this problem and how to fix it.

1. Start Amazon Linux 2 and sign in. (I recommend an m6g.medium instance

Tested on macOS:

1. Install the CodeLLDB VSCode extension. Unlike the debugger in the C/C++ extension, this allows to set breakpoints inside Zig "test" blocks (in the MS C/C++ extension debugger, breakpoints inside test blocks will be disabled once the debugger starts for unknown reasons.
2. When compiling the test, tell it to also emit a binary: zig test -femit-bin=zig-out/bin/my-test src/bla.zig, otherwise there will be no executable to debug.
3. The compiled test executable expects the path to the Zig executable as first command line argument, the launch.json file needs to be setup accordingly (note the args item):
